LOUIS H. MORIN, OF NEW YORK, N. Y., ASSIGNOR TO DOEHLER DIE-CASTING (10., A CORPORATION OF NEW YORK.

VENDING MACHINE.

Application filed June 25, 1925. Serial No. 39,442.

My invention relates to coin-controlled vending machines and has for its general objects, inexpensiveness of manufacture, simplicity of construction, effectiveness in operation, the prevention of tampering with the machine, assurance of operation when the proper coin is inserted, the reduction to a negligible minimum of the possibility of otherwise operating the machine, such as by the insertion of slugs of various kinds, the continuous operative condition of the machine, assurance against breakage and more particular objects and advantages which will hereinafter appear.

My invention includes features of construction and combinations of parts as will appear from the following description.

The 'eoincontrolled vending machine illustrated in the accompanying drawings as an embodiment of my invention has some features which are common to some niachines oi this type as heretofore constructed and which will now be described, in order that my present invention may be better understood. A prior vending machine of this general type is shown in the patent to Mortensen, No. 1,517,377 of December 2, 1.924, in which some of the features of the delivery mechanism are similar to corresponding features in the disclosed embodiment of the present invention, but in which the coin-controlled mechanism is substantially different.

A case-1tor1ning base for the machine comprises an enclosing side wall 1, a flat top wall 2, shown as formed in one piece with the side wall 1, a bottom closure 3 and a removable front slide 4 guided at its edges in grooves formed in forwardly projecting portions of the side wall 1, as shown in the drawings, and provided with an inner top flange 5 which is in alignment with and forms a continuation of the top wall or base cover 2 as shown most clearly in Fig. 2. The side wall 1 is extended above the periphery of the top closure 2 to form a circumferential head 6, and the top flange 5 of the front slide d is thickened, as shown at 7 in Fig. 3, to form a continuation of the bead 6.

The top closure 2 of the base forms the floor or bottom of a package-containing magazine which includes a glass cylinder 8 which at its lower end rests upon a gasket as shown on the top of the periphery oi. the magazine bottom 2 and just within the shoulders formed by the heads 6 and 7, so that the cylinder 8 rests upon the flange 5 of the slide 4 to prevent the removal of this slide, as shown in Figs. 2 and 8. A top cover or closure 9 for the magazine cylinder 8 rests upon a gasket upon the upper end of the latter as shown in Fig. 1. A central shaft 10 ties together the base bottom 3 and the top closure 9, and the latter is removably held upon the upper end of the shalt 10 by means of a suitable lock 11, the top cover 9 being provided with an internal boss 12 for the reception of the lock 11 as shown in Fig. 1.

An inner rotative upright magazine member comprises a circumferential series of vertical equidistantly spaced peripherally open package-containing channels 13, shown as eight in number (Fig. 2) and which may be formed by suitably bent strips of sheet metal as shown in the drawings. The upper ends of the channels 13 are carried by a cupped disc 14, loosely surrounding the boss 12. The lower ends of the channels 13 are carried by a peripherally notched lower disc 15 which is shown as secured by means of a pairof bolts-16 to a flanged disc 17 which rotatively fits into an opening in the magazine bottom 2 and which loosely surrounds the shaft 10 (Fig. 8). Packages 18 to be purchased and delivered from the machine by means of purchase-delivering mechanism presently to be described, are contained in the magazine channels 13 in which they may move downward by reason of their own weight, assisted by the weight of a follower ring 19 (Figs. 1 and 10) having large internal lugs which pro ect into the channels 13. Any free upward movement of the follower ring 19 is prevented by means of a pair of releasable spring-pressed pawls 20, the inner ends of which engage rack teeth 21 formed in the inner walls of two opposite channels13, as clearly shown in Fig. 1.

The purchase-delivering mechanism employed in the carrying out of my invention will now be described. A. rotative purchasedelivering member is shown as a plate 22 located immediately beneath the magazine bottom 2 and this plate is connected to the above described rotative magazine member, including the package-containing channels 13, by means of the bolts 16, for coaxial rotative movement of said magazine member and purchase-delivering plate 22. The lower disc 15 of the magazine, the flanged disc 17 and the delivery plate 22 are all further rotatively connected together by means of a pair of lugs 17? on the upper side of the disc 17 entering holes in the disc 15 and a pair of lugs 17 on the lowerside of the disc 17 entering holes in the delivery plate 2 Also the flanged disc 17 is shown as provided with a slight upper boss over which the n'iagazine plate 15 fits and with a longer lower boss 17 which passes through and extends below the delivery plate 22. The delivery plate 22 is provided with a circumferential series of equidistantly spaced packagewlelivering openings 23 corresponding in number and in vertical alignment with the channels 13, these openings being formed by peripheral notches in the plate 22 as shown in the drawings so that the delivery plate 22 forms a star wheel.

It will now be evident that the delivery plate 22 and the above described magazine member including the channels 18 are adapted to rotate together from any one purchase-delivering osition of the plate 22 to the next succeeding delivery position and that concomitantly the said magazine memher will be rotated to correspondingly successive positions for supplying packages to the delivery plate 22. For enabling the packages 18 to be thus supplied to the delivery plate 22, the magazine bottom 2 is provided with an exit opening 24: (Fig. 2) through which the packages 18 may be dropped into the corresponding aligned slot 29 in the plate 22 a segmental lower floor plate 25 (Figs. 2, 4. and 6) being provided innncdiately below the delivery plate 22 upon which a package carried by the delivery plate may be moved along to the purchasedclivering position, for delivering a single purchase. In the particular machine illustrated in the drawings such purchase will be a single one of the packages 18.

For thus delivering a single package 18 it is to be noted that the stationary bottom plate or main floor plate 2 of the magazine is of substantially the same thickness as any one of the packages 18, and that the delivery plate 2 is also of the same thickness. so that when a package 18 is supplied to the delivery plate 22, this package will be substantially flush with the upper surface of this plate while the next following package will be retained in the package supplying opening 24- in the magazine bottom 2 substantially flush with both sides thereof. hen the plate 22 reaches its delivery position, the package carried thereby will drop into a. chute 26, and will slide down the inclined bottom of this chute into an external reception cup 27, shown as formed on the base 1. The above described rotatiw magazine meu'iber having the paclmge-containing channels 13, the delivery plate 22. below and connected thereto to rotate therewith. and the above described means for supplying packages from the magazine to the d-clivcry plate 22 do not per se form a part of my present invention but these parts. however particularly the notched plate 22, do form elements in combination in the complete coin-controlled mechanism according to my invention, as will hereinafter appear.

In accordance with my invention and as a feature of the coin-controllcd mechanism thereof, a releasable locking device. adapted to be released by a moving coim is provided and is normally clfective to stop and positively lock the delivery plate 22 togciher with the above described rotative magazine member against rotative movement in either direction away from any delivery position of the plate 2. In the machine illustrated in the drawings such locking device is shown as comprising 1 double acting locking pawl 28 pivoted within the base 1 on a vertical pivot 29 and norn'mlly pressed to its engaging position by a spring 230. being adapted to engage in the outer cndcf one of the empty package-delivering notches 28 of the delivery plate 22 thereby, as clearly ill] lUO

cry plate 22 againstrotative movement in either direction. Thus the rotatable delivery plate 22 forms also a coin-controlled locking plate and thereby becomes a partof the coin controlled mechanism, more clearly appear.

For disengaging or releasing the locking pawl 28, a coin-operated trip rod 31, which is a push rod, shown as rectangular in cross section, is provided extending substantially diametrically across the upper part of the casing 1, being guided at its forward end in a vertical. partition wall 32, which extends across the forward part of the casing 1 in spaced parallel relationto the slide 4: and bearing a substantially similar relation to a front lower flat wall portion 33 of the casing 1, and this partition wall 32 may be cast in one piece with the casing 1, or it may be a separate casting firmly secured in place therein. At its rear end the slid.- able pawl-releasing push rod 31 has a reduced portion 34 which loosely engages in a hole in the locking pawl 28, the reduced. portion 84: forming a shoulder 35 whereby rearward movement of the push rod 31 will disengage the pawl 28 from the delivery plate 22. j

The forward end of the push rod 31 normally projects through the partition 32 and. is provided with an inclined cam surface as shown in the drawings which normally in the path of the rear edge portion of a coin 36 to be engaged thereby as the coin is removed from left to right as shown in Figs. 5 and 7 of the drawings, whereby the coin 36 as it moves between the partition 32 and front slide a will push back the push rod 31 and thereby disengage the pawl 28, such disengagement of the pawl 28 being effected preparatory to a rotative purchase-delivering movement of the tie livery plate 22 and a corresponding package-supplying movement of the rotative magazine member. A. slight further forward movementof the coin 36 beyond the pawl-disengaging position thereof will carry the coin beyond the end of the pawlreleasing push rod 31, thereby permitting the pawl spring 30 again to become effective position in readiness again to stop and positively lock the delivery plate 22 at the next succeeding delivery position.

Means are provided for limiting the forward movement of the push rod 31, such means being shown as a leaf spring 31 which at its lower end is secured by means of a screw toa boss 32" formed on the inner side of the partition wall 32, the upper end of the spring 31 engaging .in a notch in the lower side of the push rod 31, as shown in 3 and 9, this spring also being effective to return the push rod to its new shown in Fig. 4, positively locking the delivas will hereinafter.

for urging the pawl 28 towards its locking.

mal forward position. As soon as the coin 36 has passed the projecting cam end of the push rod 31 the latter will be thrust forward by its spring 31 to its normal position independently of the locking pawl 28, thereby leaving the latter to be separately returned later .to its locking position without the possibility of such return movement of the pawl being hampered by the push rod, the shoulder on the push rod having moved away from the pawl 28 by reason of the reduced rear end 3 1 sliding forward in the hole in the pawl 28, as will be readily un derstood.

In carrying out by invention, mechanism as a coin-controlled feature thereof operated by the moving coin 36, and now to be described, provided for in'iparting a step of rotative movement to the combined locking and delivery plate 22 and the package-supplying magazine member from any one of the delivery positions of the plate to the next succeeding positively locked delivery position thereof. A spur gear 37, which tits over the lower end. of the lower boss 17 of the flanged. disc 17 coaxial with the delivery plate 22, fixed to this plate, as well as to the flanged disc 17 and bottom disc 15 of the packagesupplying magazine member by the bolts 16, and is further coupled to the delivery plate by means of a pair of lugs 37 on the upper side of the gear 37 which enter holes in the delivery plate 22, as is shown .in Figs. 2, 3, and l.

A second spur gear 38 which is a coinoperated drive member, forward of the central spur gear 37, meshes therewith and is fixed on the upper end Off a stub shaft 39 journaled in the boss 32 on the partition wall 32, the gears 37 and 38 being of the same diameter and having the same number of teeth so as to have unitary rotative movement in opposite directions. The drive gear 38 is provided with a circumferential series of eight equidistantly spaced abutmentforming studs 38 which project downwardly therefrom. Some one of these abutments or studs 38 is normally in the path of the moving coin 36, in position to be engaged thereby while the coin is still in engagement with the end of the coin-operated lock-releasing push rod 31, as will be clear from Figs. 5, and 7, whereby the delivery plate 22 will be in unlocked condition to permit initial rotative movement to be imparted thereto, and when, by reason of the subsequent further advance of the coin 36, the push rod 31 is disengaged thereby, the locking pawl 28, being urgedinward by its spring 30, vill ride upon the periphery of the delivery plate 22 between two adjacent purchase-deliverii'ig slots or notches 23 therein, as will be readily understood, the disengaged. push rod 31 being returned to its normal forward position by the spring 31. The traveling ooin 36 first unlocks the delivery plate 22 and then, by reason of its engagement with one of the studs 38?, rotates the delivery plate from one of its delivery positions to the next succeeding locked delivery position,

thereby assuring the delivery of a single purchase.

The means employed 1n above described, for first releasing the locking device including the pawl 28, and then to operate. the unlocked purchase-delivery mechanism to deliver a purchase, will now be described. Such means comprise a manually operable coin carrier 40 mounted for forward and backward. movement and shown as pivoted for rocking movement upon the forward end of a stud 41 fixed in the partition wall 32, which at this point is'shown (Fig. 3) as formed with a slight circular boss entering a corresponding recess in the rear face of the coin carrier, and

the portion of the stud 41 fixed in the walltion wall 32 at the back, and the front slide 4 and flat wall 33 at the front, as shown in Figs. 3 and 4. Upon its arcuate left edge portion (Figs. 5and 7) the coin-carrier 40 is provided with a projection or lug 43 for limiting the forward coin-carrying movement of the coin carrier, by engaging an upper stop lug 44 carried by the partition wall 32, and for limiting the backward or return movement of the coin carrier 40 by engagement with a lower stop 45, shown as provided on the lower end of a bracket member 46 secured to the base 1 within the casing partthereof formed between the partition 32 and the upper and lower front portions 4 and 33 of the base. This bracket 46 may be cast in one piece with the frame wall 32.

After the coin carrier 40 has been moved forward manually by means presently to be described, it is retracted orreturned to its normal position by means of a retractile spring 47 attached indirectly to the lower portion thereof, through means presently to be described, and anchored in the base 1,

as shown in Figs. 3, 5 and 7, which show the coin carrier 40 in 1ts normal or retracted position with its limiting lug 43 abutting.

against the lower stop 45. At the top and near its forward edge the coin carrier 40 is provided with a transverse coin-holding slot or notch 48 for receiving somewhat snugly but freely the lower edge of the coin 36, and back of the coin-receiving slot 48 accordance with my invention for moving the com 36 as a radially inclined shoulder 49 is provided for a purpose which will hereinafter appear. At the top of the inclined shoulder 49, the coin carrier 40 is provided with a coinpushing finger 50 for engagement with the center of the coin to be moved.

This coin-moving finger 50 is shown as formed of a separate piece of material and has a flat shank portion set into a slot in the main body part of the coin carrier 40 and shown as firmly held therein by means of pins, this slot extending through the coinholding slot 48 and continuing with considerable depth entirely around the right and lower edges of the coin-carrier, for a purpose presently to be described. The bottom of the coin-holding slot 48 is curved upwardly at the back on the arc of a circle, to

,fit snugly the edge of a coin, as shown in Fig. 3, in which the coin 36 isshown in broken lines, thereby to prevent the insertion into the slot of square or otherwise angular slugs. At the front side of the coin carrier the forward wall of the coin-receiving slot 48 projects upwardly for some distance in the form of a tapered finger 50 which forms a coin guide, this coin guide 5O being shown as a separate piece set in a notch in the main body part of the coin carrier and firmly secured thereto by means of a screw, as shown in Fig. 5. The coin-moving finger 50 has a further important func tion which will hereinafter appear.

A coin, such as the coin 36, may be inserted edgewise into the machine through an inclined coin slot 51 provided in the removable slide 4, as shown in Fig. 1, this coin slot 51 of course being of sufliciently small dimensions to prevent the insertion of slugs which may either of greater diameter or greater thickness than the proper coin. When the coin 36 has been inserted into the slot 51 it is received at its lower edge in the slot 48 in the coin carrier and passes just above the upper stop lug 44 upon which it may rest in inclined position in front of the rounded end of the coin-pushing finger 50, as illustrated in Figs. 5 and 7. As the coin carrier is manually rocked in a forward direction against the tension of its spring 47, the finger 5O pushes the coin forward with its lower edge seated in the slot 48 which, while it receives the coin freely, at the same time prevents any sidewise angular movement or rocking of the coin on the end of the finger 50.

As the coin 36 moves forward, immediately at the beginning of its movement, as will be clear from Figs. 5 and 7, its rear edge comes into engagement with the inclined cam face of the push rod 31 and pushes this rod back, thereby releasing the plate-locking device, including the looking pawl 28, as hereinbefore described and as will be readily understood. \Vhile the edge of the coin 36 is thus holding back the push rod 31, the upper forward edge portion of the coin comes into engagement with one of the abutment pins or studs 38 whereupon a slight further forward movement of the coin 2-36 will free the coin from the push rod 31, and continued forward movement of the coin will rotate the stud-carrying drive gear 38 through oneeighth of a complete rotation, thereby rotating the delivery plate 22 to its next delivery position, whereby a single purchase, comprising one of the packages 18, will be delivered as hercinbe- :t'ore described.

The coin 3G in the coin carrier 40 has now reached its final forward position. As the coin carrier 40 is retracted or moved backward by its spring 47, the upper edge of the coin, which now inclines slightly in a forward direction, will be free from the stud 38 and the coin will drop into a coin chute 59. provided in the casing 1, and thence through an opening in the partition 32 to the casing bottom 8, as shown in Figs. at and 5 of the drawings. To guard against coins falling from the bottom 3 into the mechanism of the machine, should the machine be inverted, a guard plate 59. is provided and is held up by a spring 52 against shoulders (not shown) provided in the casing 1. i y

To insure against the coin failing of its own accord to free itself from the coin carrier, so as to drop into the coin chute 52, a spring-pressed coin-disengaging pawl 53 shown as pivotally mounted on the partition wall 82 and having its hooked end projecting within the wall into the path oi the coin, will dislodge the coin from the coincarrier, it being noted in this connection that lost motion is provided between the hook oi the pawl 53 and the coin in the final position of the latter, so as to enable the upper edge oil? the coin to tree itself from ongap en'ient with the abutment stud 38, which will be clear from the drawings, particularly 5 and 7. he coin-disengaging or kick-oil pawl 53 shown as pivoted intermediate ofits length on a pivot pin 53, the hook-carrying arm of this pawl lying in a horizontal slot in the partitnon wall 32, the tail of the pawl being urged away from the rear of the wall 32 by a compression spring 53", the spring-pressed movement pf the pawl being limited by the boss 82, and the outer face of the 11001: of the pawl being); inclined. to term a cam surface, whereby the hooked arm of the pawl will be moved rearwardly by the advancing coin, as shmvn most clearly in Figs. 5, 7 and 9.

In order to provide for the tree and unobstructed automatic return of the locking pawl 28 to its locked position shown in Fig. 4: when the coin carrier 4C0 has been rocked lorward to the right as viewed in 5 and 7, so that its shoulder 49 has passed beyond the inclined cam end of the pawl releasing push rod 31, the peripheral part of the coin carrier 40 is cut away or provided with a groove 54L adjacent the partition wall 32, as shown in dotted lines in Fig. 7 It is to be noted that as soon as the coin carrier is rocked away from its normal position shown in the drawings, it will block or close the coin slot 51 against the insertion of a coin, thereby assuring proper operation of the machine and preventing loss of coins, as will hereinafter more clearly appear.

Normally, or when no coin is carried by the coin carrier 40, the coin carrier is free to be rocked idly and harmlessly forward and back between the limits of its stops 4:4: and 1.. In order to assure the proper operation of: the machine and to prevent the loss of coins therein, means are provided which, when a coin is carried by the coin carrier, operate automatically to prevent backward or return movement of the coin carrier 4:0 from any intermediate point of forward movement between its stops l4 and 45, thereby, when the coin carrier carries a coin, compelling a complete forward movement of the coin carrier before it can have any return movement; such means, when no coin is carried by the coin carrier, also operating auton'iatically to permit the coin carrier to be returned by its spring 47 from either its final forward position or from any intermediate position of forward movement to its normal retracted position shown in the drawings, thereby to uncover the coin slot 51 so that the machine will be in a condition to receive a coin for ell'ecting a purchasedelivering operation thereof. In the illustrated embodiment ol the invention such means comprise a pawl-and-ratchet device controlled by a teeler which in turn controlled by a coin, thereby to control the movements oil? the coin carrier in the manner above described; and the particular mechanism illustrated as comprised in such means will now be described.

A three-armed lever 55 formii'lg a ieeler, is located in the hereinbeiore mentioned long, deep slot in the coincarrier 4:0 and is pivoted to the lower part of the coin carrier by means of: a pivot pin 56. The long, curved upper arm 55 of the lever 55 forms a feeler tinge-r tern'iinating in a i'ecler tip 55; the restoring); spring 41:7 for the coin carrier is connected to the short arm 55 which extends downward and laterally at an inclination to the right, as viewed in Figs. 5 and 7 and the remaining; arm 55 extends laterally to the left and at its free end has pivoted thereto, by means of a pivot pin 55, a pair of reversible pawls 57, one at each side of the arm 55, each pawl 57 having an arm to wlrch connected a small retractilc spring, L h

'"wliieh anchored to the pivot late position, in which the I engagement with the ratchet 58, and then pawl 57 at the intermediate position thereof shown in the drawings, each pawl having a free pawl end which projects radially in rela tion to the pawl pivot 55 and which in the positions of the parts shown in the drawings is also radial to the pivotal axis of the coin carrier provided by the pivot studs 11 and 42. A ratchet bloc: 58 provided with areuately arranged saw-tooth ratchet teeth in the path of the free ends of the pawls 57 is fixed in the casing adjacent the bottom closure 3 and adjacent the left side of the easing part formed between the casing walls 32 and33, as shown in Figs. 5 and 7. The

* coin carrier spring 47 besides having a tendency to return the coin carrier 40 to its normal retracted position shown 1n the drawmgs, also at the same time normally has a tendency to hold the upper free end of the feeler finger 55 in engagement with the ,.bottom ofthe slot in the coin carrier, as "shown in Figs. 5 and 7, and thus to yieldiingly hold the pawls 57 in the position shown in which they are yieldingly urged .outwardly'towards the ratchet 58. In this connection it may be noted that the pawls 57 are shown as having square-cornered ratchet-engaging ends and that the teeth of the. ratchet 58 are correspondingly shaped. At the end of each complete movement of g the coin carrier .40 in either direction, the

pawls 57 pass beyond and are free from the ratchet 58, as is shown in Figs. 5 and 7 for the normal or retracted position of the coin carrier. At the beginning of each movement, in one direction or the other, the angular position of the pawls 57 is reversed when they strike the end of the ratchet, so that thereby the pawls will wipe over the ratchet 58 in each direction of complete movement of the coin carrier 40.

'As hereinbefore mentioned, and by means hereinafter to be described, the coin carrier 40 may be manually rocked against the tension of its restoring spring 47, in the forward direction, that is, clockwise as viewed in Figs. 5 and 7. When thus rocked throughout a complete movement in the forward direc- I thereby uncovering the coin slot 51 in the casing and also leaving the coin carrier in position to receive a coin in its coin-holding slot 48.

.Should the coin carrier 40 when it carries no coin be rocked forwardly to an intermedipawls 57 are in released, the pawls 57 per so will have a tendency to prevent a return movement of the coin carrier, but such tendency is overcome by reason of the fact that the mutual relation of the several lever arms, comprising the spring connected arm 55 of the feeler lever 55, the pawl-carrying arm 55 and the pawls 57 themselves, is such that the coin carrier spring 17 is caused to apply a more strongly effective force toward returning the coin carrier than it is caused to apply toward holding the pawls 57 in locking engagement with the ratchet 58, with the result that the pawl-carrying arm 55 yields away from the ratchet 58, thereby permitting the pawls 57 to trip and reverse, thus disabling the pawls, so that they are unable to prevent return movement of the coin carrier.

When the pawl-carrying arm 55 thus is moved away from the ratchet 58, the feeler lever 55 as a whole rocks on its pivot 56 and the feeler tip 55 thereof moves across the empty coin-holding slot 48 which is in its path. After the pawls 57 have been disabled as above described, the feeler lever 55 may return to its normal position in which its feeler tip 55 clears the coin-holding slot 18, and the disabled pawls 57 may wipe over the teeth of the ratchet while the coin carrier is returned to its normal position by the spring 47, in which position it may receive in its coin-holding slot 18 a coin inserted through the uncovered coin slot 51. The above described manner of operation is important in view of the fact that should a customer find the coin slot 51 closed, he might think that the machine was out of order and leave it without having made his intended purchase.

When the coin carrier 40 carries a coin it is positively locked against backward movement, by reason of the fact that a coin, such as the coin 36, in the coin-holding slot 4-8 blocks the path of the feeler tip 55" of the feeler finger 55 and forms an abutment therefor which prevents the pawl-carrying arm 55 from moving away from the ratchet 58 to a suflicient extent to release the pawls 57, as will be clear by an inspection of Figs. 5 and 7, thereby preventing backward move ment of the coin carrier from any intermediate position and compelling a full torwa rd movement thereof and discharge of the coin therefrom, after which the spring 17 may return the coin carrier to its normal position shown in the drawings. This manner of operation is of importance because it has been found that to and fro movement of the coin carrier while it carries a coin is almost certain to dislodge the coin, which is then lost in the machine, without a purchase be in delivered thereby.

it will now be evident that the above described automatically acting mechanism in control of the movements of the coin carrier 10, operates to prevent back\ and movement of the coin carrier when the latter carries a coin, and to permit free baclnvzml movement of the coin carrier from any post ill) tion thereof when no coin is carried thereby, substantially the same, in the latter respect, as if such mechanism Were not present. That is to say, as stated in terms of results, such mechanism is effective to prevent loss of coins in the machine, and is also effective to guarantee that the machine shall be left in normal condition, to permit the insertion of a coin therein. Therefore, the prime purpose of such mechanism is to prevent backward movement of the coin carrier 10 when it carries a coin, and then only.

In carrying out the invention, automatically acting means are provided controlled by the supply of packages 18 in the magazine for preventing the insertion of a coin into the machine when the magazine needs replenishing, such means being adapted to lock the coin carrier at its above described slot-closing position and also to lock the above described purchase-delivering mechanism against operation independently of the locking device including the locking pawl 28. As a precaution against a condition in which some of the aackagerontairr ing channels 13 may contain a few more or a few less packages 18 than others, .aid slot-closing and locking device is adapted to become effective before any of the channels 13 become entirely empty. The means shown in the drawings for thus controlling the coin carrier 10 and concomitantly locking the purchase-delivering mechanism will now be described.

The follower ring 19, because of the fact, as above described, that its large teeth or lugs enter the package-containing channels 13, must necessarily partake of the rotative movement of the magazine member of which these channels form parts. On the lower side of its peripheral edge part the follower ring 19 is provided with a plurality, shown as four in number, of equidistantly spaced downwardly projecting lugs 59 (Figs. 1, 10 and 11) which are located circumferentially to one side of or out of alignment with the large internal lugs or projections thereon, as shown in Fig. 10, and therefore correspondingly out of alignment with the packages 18 and channels 13, and which are adapted to engage in a corresponding se ries of openings or holes (FigsQQ and 3) in the bottom plate 2 of the magazine before the magazine becomes entirely empty of packages.

The lugs 59 and openings 60 have abrupt engaging faces adapted to abut in the clockwise forward movement of the ring 19, but the reverse faces of the lugs 59 and openings 60 are inclined, as shown respectively in Figs. 11 and 2, so that the lugs 59 may glide gradually into the openings 60. It will be evidentthat these lugs 59 when the magazine becomes nearly empty will slide around upon the magazine bottom or floor 2 and at the completion of a one-fourth rotation of the ring 19 will enter the openings 60 and thereby locletlie rotative magazine member against rotative movement in the forward direction and will also lock the entire purchase-delivering mechanism against operation. Obviously, only one locking lug 59 and one opening 60 could be employed, but in that case a complete relative move mentof the magazine might in some cases be required before the locking operation tool; place and the results would not be so accurate.

The circumferential location of the lugs 59 and openings 60 are made such that the above described locking operation takes place just prior to the complete or final purchasedelivering movement of the delivery plate 22, but at a point in which the packagecarrying delivery slot 2-3 in the delivery plate has moved beyond or to a sufficient extent past the edge of the package-guiding segn'iental floor plate 25 and over or to a suiticientextent over the top of the delivery chute 26 to permit the package carried by the delivery plate 22 to drop into the chute 26. T he purchase-delivering plate 22 thus locked by means of the lugs 59 independently of and at a rotative position before the looking pawl 28 can become effective to lock this plate and the other parts of the purchasedelivering mechanism. This locking of the purchase-delivcring plate 22 before it has quite reached its final purchase-delivering movement obviously at the same time locks the stud-carrying coin-operated drive gear 38 at a point before it has quite completed a step of its rotative movement. In this condition the coin carrier 40 is prevented from completing its forward movement by reason of the fact that the coin 36 abuts against a stud 38 of the locked gear wheel 38, and also the coin carrier 40 is locked against backward or return movement by reason. of the fact that the locking pawls 57 of the coin carrier are in locking engagement with the ratchet 58 so that the coin carri u 4.0 is thus locked against movement in either direction and in a position in which it closes the coin slot 51, thereby elfectively prevent-- ing the loss of coins in the machine when the magazine needs replenishing.

The means provided according to my in vention for manually in'iparting rocking movement to the coin carrier do will now he described, reference being had more particularly to Figs. 5, 6 and 7. The coin carrier 40 is provided with an internally toothed segmental rack 61, formed in an elongated opening through the coin carrier. The rack 61 is engaged by a tubular pinion 62 which at its outer end carries a head 6 t which has a bearing in a boss 65 formed on the outer side of the front casingwall. 33, the pinion 62 and head 64: preferably being formed in a single piece, as shown in Fig. 6. This pinion 62 has an inner reduced end, shown in dotted which passes inwardly loosely through the headed pinion 62 and is shown as projecting at its inner end beyond the partition wall 32 and pinion 62 in which its ournaled. The inner end of the pinion 62 as well as the boss on the inner side of the partition wall 32 together with a washer forms an abut ment for a coiled thrust spring 68 which is held under tension by an adjusting nut 69, together with a washer on the inner end of the handle shaft 67 j Yieldable driving means are provided for operatively connecting the handle 66 to the pinion 62, such as a friction clutch, and in the illustrated embodiment of the invention a cone clutch is employed for this purpose. The pinion head 64 forms the cup element of the clutch and the cone element 70 thereof is providedwith a diametral tongue or ridge 71 having abrupt engaging faces and which seats in a groove complementary thereto in the inner end of the handle boss 66, so that the cone clutch element 7 0 is positively locked to the handle 66 for rotative movement therewith. The amount of force required to cause the cone element 7 O to slip in the cup element 64 maybe regulated by means of the nut 69 on the inner end of the handle shaft 67.

The cone clutch element 70 grips the cup element 64 with sufficient firmness to permit the handle 66 to impart rocking movementto the coin carrier 40 in the normal operation of the machine. However, should any attempt be made, in tampering with the machine, to force the coin carrier beyond its limits of movement, or to reverse its direction of movement at an intermediate point, when it carries a coin, or to impart movement thereto in either direction during the above described locked condition of the machine in which the magazine needs replenishing,. the clutch will yield, the cone element 7O slipping on the cup element 64, permitting thehandle knob 66 to be turned idly thereby safeguarding the mechanism of the machine against possible breakage through undue force applied to the handle 66 in an attempt to operate the machine in an improper way. This continuously engaged friction clutch drive is of further particular advantage in preventing the breaking of operating Jarts of the mechanism in view of the fact that the operating power applied to the handleknob 66 is multiplied or in:

creased by means of the speed-reducing gearing comprising the pinion 62 and rack 61 on the coin carrier 40.

In this connection it is to be noted as of importance that regardless of any amount of slippage of the clutch, the handle knob 66 will be left in. a suitable position for operating the machine, or, in other words, the handle 66 has a universal operating position, this being by reason of the continuous gripping action of the friction clutch, and which would not necessarily be true as to some other forms of clutches. Thus the inserted coin will become immediately ell'ective to operate the machine. Otherwise, the customer would be annoyed by the idle turning of the handle knob, with no immediate result, after he had inserted-the coin, and would be likely to conclude that there was something wrong with the machine.

Another important advantage, which has proved in commercial use to be very desirable in a vending machine, is that the smoothly operating friction driving clutch shown as employed as a feature of the invention is silent and will slip without noise, which is not true of some forms of yielding clutches. It has been found that a vending machine drive clutch which makes a snap ping noise when the clutch elements move relatively to each other will cause children and others to persist in rotating the handle knob merely to play with the machine and to amuse themselves.

It is to be noted that the pinion 62 and rack 61 constitute speed-reducing gearing which not only multiplies the power applied, to the handle knob 66 for operating the mechanism of the machine but also results in a relatively slow and uniform movement being imparted to the entire mechanism, thereby preventing jars and shocks thereto which might result in damage thereto or breakage thereof. It will now be evident that the rotatable plate 22 and the gears 37 and 38 are operated and controlled by the coin, that the purchasing-deliverying 1necha nism per se is operated through its connection to the gear 37, and that the plate 22 has two'functions by reason of the fact that,

in the particular machine illustrated, it is both a coin-controlled locking plate and a delivery plate as well. Also it will be noted that the coin-released locking device locks the delivery mechanism as well as the coin operated drive member 38. Because of the considerable weight and momentum of the loaded magazine, it is desirable that it should be stopped and locked at a point as near thereto as possible. Obviously in a machine of a diiferent type the locking might take place at a different point, for example, at the coin-driven member 38 or at its shaft 39. Also in such a machine the delivery mechanism might be operated directly from lll) the shaft 39, the intervening gearing then being omitted.

In carrying out my invention protective means or safeguarding devices are provided to guard against the machine being caused to operate to deliver packages without insertion of coins and such means vill now be described. One of the ways in which attempts are sometimes made to tamper with a machine of this type in the hope oi? causing packages to be delivered without inserting a coin is to grasp the machine and violently twist or whirl it around as a whole in an attempt thereby to cause the package-containing magazine member to rotate by reason of its weight and moi'nentum, and thus operate the delivery mechanism. In the machine oi. my present invention, and as hereinbetore described, it is to be noted that in the normal position of rest of the parts of the machine the delivery plate 22 together with the package-carrying magazine member is positively locked against either forward or backward rotative movement, by the double acting locking pawl 28, thereby rendering any such improper operation of the machine impossible.

It in the hereinbetore described condition of the magazine in which it requires replenishing anatteinpt should be made to obtain packages by whirling the machine, this result could not be accomplished by reason ot the fact, as hereinbctore described, that the delivery plate 22 would then be positively locked against forward movement by reason of the engagement of the lugs 9 of the follower ring 19 in the openings in the magazine bottom 2, and backward or reverse movement ot the delivery plate 22 would be prevented by the coin 36 which is held by the locked coin carrier 4.0 against one of the studs 38 of the drive gear 38 as hereinbeiiore described.

motion. to the machine.

While it would be ditlic'ult to advance the loaded coin carrier only as far as and stop it at an intermediate position in which the locking pawl 28 is held in disengaged position by the edge of the coin, even then there would be no possibility oi. obtaining packages by imparting a whirling or twisting It the maganine member and delivery plate 22 could then be made to move forward the next advancing stud 38 would strike the upper edge of the coin and tip it forward out of the coinholding slot 48 in the coin carrier and into the coin chute 52, and in case the delivery plate 22 should complete its delivery movement, only a single package paid for by the inserted coin would be delivered by reason oi? the fact that the locking pawl 28 would become effective at the first delivery position reached by this plate and would lock it there Means in accordance with. my invention are provided to prevent the machine being caused to deliver a package by the insertion therein oi a paramagnetic slug such as iron or steel. and which might be of the same dimensions the coin 36. The subject matter relating to this teature of my invention has been embodied in a divisional application, Serial. No. 133,615, filed September 4:, L926, which bocan'ie Patent No. 1,657,836, January til, 1928.

A generally ll-shaped laterally curved horseshoe magnet 72 rests at its bent middle portion upon. a small rounded lug in a notch provided between the lower stop lug 45 and the lower part of the bracket 46 which carries this lug and is comparatively loosely held in. place by the rounded lower end of an inclined pin 73 carried by and shown as screwed into the bracket 4.6, so that the magnet 72 is free to have a slight lateral rocking movement. The laterally curved arms of the magnet 72 extend at an inclination over and normally rest upon the upper stop lug 44 and terminate somewhat beyond the initial position of the inserted coin 36, as shown in F" 1s. 5 and 7. Normally the magnet arms held in contact with the upper stop lug n by means of a pair of springs 74; carried by the magnet on pins 75 and 7 5 and hearing at their upper ends against the upper portion oi the bracket 46, one o'l these springs appearing in Fig. 5 and the other in Fig. 7. The upper end of the inner magnet arm or that adjacent to the partition wall 32 is beveled or cut away at the top on a horizontal plane so as to clear the studs 88 as the gear E58 is rotated and as shown in the drawings, perhaps most clearly in Fig. 7.

When a coin is inserted in the machine it comes into contact with the magnet arms and pushes them slightly aside against the tension of the magnet springs 74, the outer magnet arm imparting a final inward impulse to the coin, which is received at its upper edge into the space between the magnet arms, as is shown in 5 and 7. Thus the coin, such as 3", will be held in the coin carrier slot 4-8 by the magnet arms and will be securely retained in the machine, inward from the coin. slot 51 and free therefrom, by the outer arm of the magnet 7 2, so that the coin cannot fall out of nor be extracted from the machine. It will be noted that the magnet 72 is thus utilized to'perform a desirable mechanical function independently of itsoperation as a magnet.

When the coin carrier 40 is rocked in the forward direction, the coin 86 is carried treely away from the ends of the arms of the magnet 72. The magnet 72 is provided with a lower roller 76 and an upper roller 76, between the magnet arms and journaled respectively on the lower and upper springholding pins 7 5 and 7 5. The stop-engaging lug 43 on the coin carrier 40 is provided with a tapered projection 77 which normally enters slightly between the arms of the mag- "netjust below and substantially in contact with the lower roller 7 6 as shown in Figs. and 7. When the coin carrier 40 is rocked in its forward movement the inclined cam projection 77 bearing against the roller 7 6 iwill immediately raise the upper ends of the strike the upper stop lug 44. A similar acmagnet arms, and when the projection 7 7 has moved upwardly beyond the roller 76 the springs 74 will cause the'magnet arms to tion will take place as the projection 77 passes the upper roller 7 6 Should a magnetizable slug of substantially the dimensions of the coin 36 be inserted into the machine the raising of the magnet arms as above described will lift the slug and raise its lower edge out of the coinholding slot 48 in the coin carrier 40. When similar jolt the magnet 72 has thus lifted the magnetizable slug out of the coin-holding slot 48,

and the slug will drop into the coin-chute 52, without the purchase-delivering mechanism of the machine having been operated.

Should a washer be inserted into the machine through the coin slot 51, in an attempt thereby to obtain an unpaid for package, as the coin carrier 40 is moved forward its coinpushing finger 50, which constitutes a Washer catch, will pass freely through the hole in the washer, this action being facilitated by reason of the upper edge of the washer being held back by frictional engagement with the spring-pressed magnet 72. As the coin carrier continues to advance the washer will tilt or rock out of the slot 48 and will be guided by the finger 50 until it rests upon the inclined shoulder 49 of the coin carrier. The washer thus resting loosely on the shoulder 49 in a greatly inclined position will I be incapable of operating the lock-releasing abutment stud 38 operated by a coin. Then the coin carrier push rod 31 and will pass freely beneath the which is in position to be 40 reaches the forward limit of its movement and strikes its upper stop 44 it will toss the washer into the chute 52.

Should a paper or cardboard or similar disc be inserted, in an attempt thereby to opcrate the machine, such disc will be bent, crushed and mutilated by the projecting cam end of the lock-releasing push rod 31 without operating the latter, and will be further bent, crushed and mutilated by striking against a stud 38 of the locked drive gear 38, and finally will be dumped by the coin carrier into the chute 52. A thin and readily bendable metal disc would be disposed of in a similar manner.

If a slug of somewhat less diameter than the proper coin should be inserted, such a slug will move freely past the end of the push rod 31, as is clear from Fig. 3, and will also move freely below the locked studs 38" and will be dropped into the chute The hereinbefore described free idle movement which the coin carrier 40 is permitted to have, that is, without operating the delivery mechanism, provides for ellcrting the above described disposition of the various kinds of slugs so as thereby to leave the coin-receiving slot 48 in the coin carrier unobstructed and the machine in condition for a purchase-delivering operation upon the insertion of a coin in the coin slot 51. The hereinbefore described guard devices by reason of which the machine is rendered oper able to deliver a purchase when the proper coin is inserted and is rendered non-operable by the various kinds of slugs, may be designated as selector mechanism, in that such mechanism discriminates between the proper coin for operating the machine and the various slugs, and also such mechanism constitutes rejector mechanism in the respect that slugs such as above mentioned are discarded thereby without operating the purchase-delivering mechanism of the machine.

It is to be noted that in carrying out my invention a maximum number of guard. devices are provided to prevent either the obtaining of unpurchased packages or the disabling of the machine. Also it is to be noted that the construction of the machine of my invention is such as to assure its proper operation to deliver a purchase when the proper coin is inserted therein with no liability of the coin being lost in the machine. The operation of the machine has been hereinbefore described along with the description of its construction. It may be added that machines have been constructed in accordance with the accompanying drawings and have been effectively operated and tested in the manner herein described. However, While I have discloFed herein a practical embodiment of my invention. it is to be understood that various modifications may be made in the construction shown in the drawings and above particularly described, within the principle and scope ol my invention as pointed out in the appended claims.
